The way things work not only in the overclocking world, but in most industry is that research into a bigger/better/cheaper alternative to something does not occur until it is seen as the lagging piece of the puzzle. For example, the whole memory bandwidth problem inherent to today's videocards was not investigated into until it was realized that it is the limiting factor in its performance. The current radiators being used in watercooling rigs if equipped with a decent enough fan are more than adequate in keeping the coolants fairly close to room temperature. When and if they actually become the limiting factor in watercooling, then you may see more work and research being done into the radiators. Until then, price and usability are much more important than trying to get the highest performing radiators out there. The biggest problem in watercooling is on the opposite side of the radiator. It is how to pull 75 watts of heat off of a piece of electrical equipment that has less surface area than a dime. Once that is mastered, then perhaps, the radiator will become the limiting factor and we may very well see educated comparisons between them.
